Do you know phy address of RTL8211E? Is it visible at mdio bus (/sys/slass/bus/mdio_bus if I'm not mistaken)? RTL8211E phy address may conflict with internal switch phys (addresses 0-4).
And port 5 statistics swconfig dev mt7620 port 5 show may be helpful.

xromansx · October 8, 2020, 4:30pm

this shows on boot so I think it's port 5.

123serge123 · October 9, 2020, 3:50pm

Port 5 is MAC layer. Ports 0-4 are connected to internal fast ethernet phy (100Mbps max).
But port 5 is connected to external gigabit ethernet phy RTL8211E. To correctly configure RTL8211E must be connected to mdio bus and have unique address. If internal phy is not disabled this address must be in 5-7 range. Specs says that RTL8211E phy address may be configured in 0-7 range by pullup/pulldown PHY_AD0, PHY_AD1. PHY_AD2 (pins 34,35,13 for RTL8211E). If address is known (e.g 7) than add to dts-file:

		phy7: ethernet-phy@7 {
			reg = <7>;
			phy-mode = "rgmii";
		};

In this case RTL8211E must be visible at mdio bus and can be configured by realtek phy driver.

I think port 6 is CPU so swconfig doesn't give any usefull info...and /sys/slass/bus/mdio_bus has multiple folders don't knoe exactly the structure.

123serge123 · October 11, 2020, 8:02am

Why? Try 7
And show bootlog and output of commands:

ifconfig -a
swconfig dev mt7620 show

Simply find devices sudir and phy_id file (RTL8211E phy_id is 0x001cc915).

But link still doesn't go up. I think best thing would be to find uout from u-boot but don't know how...

I think you don't need force link to 1Gbit. And switch config is incorrect. Vlan is enabled by default

But there is no vlan created. Disable vlan or create vlan1 with untagged ports 5 6
So try this variant:

	port@5 {
		status = "okay";
		phy-mode = "rgmii";
		phy-handle = <&phy0>;
	};
	mdio-bus {
			status = "okay";
			phy0: ethernet-phy@0 {
				reg = <0>;
				phy-mode = "rgmii";
			};
		};

And configure switch with commands:

swconfig dev mt7620 set reset 1
swconfig dev mt7620 set enable_vlan 1
swconfig dev mt7620 vlan 1 set ports '5 6'
swconfig dev mt7620 set apply 1

Or totally disable vlan:

swconfig dev mt7620 set reset 1
swconfig dev mt7620 set enable_vlan 0
swconfig dev mt7620 set apply 1

with config you purpose I have:

[    1.622333] gsw: setting port4 to ephy mode
[    1.631149] libphy: mdio: probed
[    1.638760] mtk_soc_eth 10100000.ethernet: connected port 5 to PHY at mdio-bus:00 [uid=03a2940d, driver=Generic PHY]
[    1.660018] mtk_soc_eth 10100000.ethernet: loaded mt7620 driver
[    1.672567] mtk_soc_eth 10100000.ethernet eth0: mediatek frame engine at 0xb0100000, irq 5
[    1.689611] rt2880_wdt 10000120.watchdog: Initialized

checged config to :

&ethernet {
	pinctrl-names = "default";
	pinctrl-0 = <&rgmii1_pins &mdio_pins >;
	mtd-mac-address = <&factory 0x4>;
    ralink,port-map = "wllll";
	mediatek,mdio-mode = <1>;


    port@5 {
		status = "okay";
		phy-mode = "rgmii";
		phy-handle = <&phy1>;
	};
	mdio-bus {
			status = "okay";
			phy1: ethernet-phy@1 {
				reg = <1>;
				phy-mode = "rgmii";
			};
		};

};

&gsw {
	mediatek,port5 = "gmac";
};

Same result , alwais showes ethernet cable not connected.

I see two different logs. In 1st:

xromansx:

Port 5:
        mib: Port 5 MIB counters
TxGPC      : 0
TxBOC      : 0
TxGOC      : 0
TxEPC      : 0
RxGPC      : 7
RxBOC      : 0
RxGOC      : 854
RxEPC1     : 0
RxEPC2     : 7

        enable_mirror_rx: 0
        enable_mirror_tx: 0
        pvid: 0
        link: port:5 link:up speed:1000baseT full-duplex

and in 2nd:

xromansx:

Port 5:
        mib: Port 5 MIB counters
TxGPC      : 0
TxBOC      : 0
TxGOC      : 0
TxEPC      : 0
RxGPC      : 0
RxBOC      : 0
RxGOC      : 0
RxEPC1     : 0
RxEPC2     : 0

        enable_mirror_rx: 0
        enable_mirror_tx: 0
        pvid: 0
        link: port:5 link:down

Can you reproduce 1st case and show logs again?
BTW something wrong in this commands:

xromansx:

root@OpenWrt:/# swconfig dev mt7620 set reset 1
root@OpenWrt:/# swconfig dev mt7620 set reset 1
root@OpenWrt:/# swconfig dev mt7620 set apply 1
root@OpenWrt:/# swconfig dev mt7620 show

I suggest to disable vlan or to define vlan 1 ports. You simple reset switch.

To simplify discussion let's see schema:

           mt7620 switch
          +------------+
eth0 <==> |P6          |
          |            |
          |P5 <==========> phy??(0-7)RTL8211E
          |         +--------^
          |         |  |
          |P4 <==> phy4|
          |         |  |
          |P3 <==> phy3|
          |         |  |
          |P2 <==> phy2|
          |         |  |
          |P1 <==> phy1|
          |         |  |
          |P0 <==> phy0|
          +------------+
                    ^
                    |
mdio bus <----------+

where
<====> - network dataflow
<---> - mdio phy managment dataflow

In case of correct config any sent packet through eth0 (ifconfig eth0 TX packets statistics) must increase received packets of P6 (Rx* statistics for port 6)
and increase transmitted packets of P5 (Tx* statistics for port 5).
And vice versus: eth0 recieved packets increase Tx* of P6 and Rx* of P5 statistics.

As you see in 1st log P5 link is up and Rx* statistics shows received network data. But no recieved packets in eth0 statistics and you don't show P6 statistics.

it was when I put : mediatek,fixed-link = <1000 1 1 1>;
But I never received link connected on PC side always Network Cable Unpluged.

Only in one case I have that uninitialized connection on PC with OpenWRT booted when I don't initialize ethernet at all and it stays connected from u-boot initialisation.

The main question was:
Can you reproduce 1st case and show logs again?

xromansx · October 14, 2020, 12:56am

This is when I set :
mediatek,fixed-link = <1000 1 1 1>;

But as I told I never got any traffic on the interface also switch port doesn't even lingt up like cable not pluged.
